Adults have been recorded on wing from June to August.[4]

The larvae feed on Plantago coronopus, Plantago lanceolata and Plantago maritima. The young larvae mine the leaves of their host plant. The mine has the form of a short, narrow gallery, made in the young leaves. Older larvae bore in the rhizome of their host plant.[5] The larvae have a yellowish white body with salmon coloured length lines and a blackish brown head. Mining larvae can be found in autumn. The species overwinters in the larval stage in the rhizome.
